Crest Audio PL6001 - User Manual

Product Description
The Crest Audio PL6001 professional power amplifier is
designed to achieve unsurpassed sonic performance and long-
term reliability—even when operating under extreme stress—in
touring or fixed installation applications.
Absolute sonic accuracy is the hallmark of every Crest amplifier.
Bass is solid and defined to the limits of audibility, with ample
current reserves delivered by an “over-engineered” power supply
and advanced Class H circuitry. Wide-bandwidth output devices
assure detailed, transparent high frequency response. And, thanks
to Crest’s exclusive IGM circuit, the PL6001 will drive 2Ω loads
safely without compromise in performance.
Construction and Quality Control
The PL6001 is built exclusively in Crest’s own USA manufactur-
ing facility, with internal components selected for premium qual-
ity and proven durability. Each modular subassembly is pre-test-
ed, and the assembled PL6001 receives a rigorous “hot room”
burn-in before thorough final checkout on precision test equip-
ment.
PL6001 Features
• Crest’s legendary “overbuilt” power supply
• Toroidal power transformer
• Latest generation of high-speed, wide-bandwidth output
devices
• Twin tunnel cooling with back-to-front air flow
• Dual, variable speed DC fans
• Massive, extruded aluminum heat sinks
• Balanced XLR and 1/4-inch (TRS) inputs
• 5-Way Binding Post Outputs
• Stereo/parallel/bridged mono mode selector switch
• Ground lift switch
• TourClass
®
protection circuits:
- ACL (Active Clip Limiting) prevents speaker damage with
gentle gain reduction at clip threshold.
- IGM (Instantaneous Gain Modulation) monitors speaker
loads to detect conditions that may overstress output
devices, allowing safe operation into nominal 2Ω imped-
ances.
- AutoRamp gradually increases gain to attenuator setting
level when amplifier is turned on.
- TourClass also includes comprehensive thermal manage-
ment, and short circuit, DC voltage, turn-on/off transient,
current inrush and sub/ultrasonic input protection.
• Input sensitivity selection
• Recessed, stepped attenuators
• Front panel circuit breaker switch
• Modular construction
• Three-year warranty
